120Hz Samsung 2233RZ LCD versus CRT monitor at 120Hz

August 22nd, 2009 · 9 Comments · Other S3D Tech


As you probably know the 22″ Samsung 2233RZ LCD display is one of the first two true 120Hz LCD monitors available to the general public with the other one being the ViewSonic VX2265wm FuHzion. These are the two displays that usually go with Nvidia’s GeForce 3D Vision shutter glasses, providing great Stereoscopic 3D experience, but these monitors are also quite good even when used by themselves in normal 2D mode for gaming of course. And in order to see how good these new displays are are I took and old CRT monitor and compared it to Samsung 2233RZ with both running at 120Hz in clone mode, showing the same image. I opted for Counter Strike Source although not a big fan of the CS games, because the original CS game ca run up to 100Hz maximum, and the Source version is capable of playing at 120 hertz or frames (fps) which is more appropriate to be used when talking about the LCDs. Of course the v-sync was enabled in order to prevent the tearing of images while playing the game, so this problem is gone, however you can still notice the bit higher input lag of the LCD compared to the CRT display. You can watch the HD video above to see what are the differences and they are not much, because the two displays are pretty close in terms of response times with the LCD being in advantage here, because of better brightness, contrast etc. Use the pause button to be able to easily compare stop frames on both screens to get better idea, but here are also some stop frames in Full HD resolution taken from the original video, before being edited and uploaded to youtube.



What you can clearly see from these stop frames is that both displays are pretty close in terms of results with most of the time getting absolutely the same result on screen or with the Samsung LCD providing a bit better one. Still there are a few times where the LCD is a bit behind and in some situations you can actually see a triple image on a stop frame while the CRT has only double objects (the last freeze frame). But this can as well be considered to be an advantage, because this happens in some times where you actually have very fast moving objects and the triple image you see on the freeze frame actually makes it seem more fluid. Also have in mind that the displays run at 120Hz (120 fps) and the video is being shot with a camera running at 25 frames per second, but I also did some interesting comparisons shooting fast moving objects with 240 fps video (double the frame rate you get displayed). I’m still working on these videos, but I’ll also publish them here along with some videos comparing the 120Hz LCD to a normal 60Hz LCD monitor, so stay tuned… ;)

    did you notice any significant advantage considering ghosting on any of the monitors ?

    There is still some ghosting on the 120Hz LCD, but much harder to notice with naked eyes and with the camera, well… I can record ghosting on both displays. You can say that these new 120Hz panels are really what was needed to actually offer something to compete with a really good CRT capable of high refresh rate on high resolution. And that said especially when talking about gaming use and especially for fast paced FPS games like CS or other similar shooters (for 3D Vision it is another thing). Another good thing that is more apparent when compared to a 60Hz LCD is the lack of so much visible tearing when panning quickly inside a game (another video coming soon). But as I said, both displays are pretty close to each other in terms of ghosting present etc. when running at 120Hz, but the LCD has some additional advantages… and if you compare to a 60Hz LCD you can actually see much bigger difference between the 60 and 120 hertz LCD panels.

    Didn’t even read your blog. Images said it all. LCD is better IMO.

    nice report, thanks a lot.

    I am not sure if you noticed.. but to me it looks liked your CRT was capped at 60Hz as shown by the flicker. but I could be wrong.

    nice work!
    a specific question arises, did u drive the lcd with 120 Hz progressive or how? does it accept 120 Hz input or up to 60-70 Hz as the conventional ones?

  • 7 Bloody // Jan 13, 2010 at 12:29

    The Samsung 2233RZ LCD display accepts 120Hz input.

    Man, this is the worst image on a CRT monitor I have ever seen. I never get such colors on my IBM monitor! I still wonder how the LCD technology utilizes better image quality?

    The CRT looks like that because your digital camera cannot pick up the flickering on a CRT monitor fully you fucking idiot. CRT will always look like this, when captured on video they will show lines going down the screen. Even if it looked like this in real life all you would have to do is adjust the red/blue prominence.
